NMR Tube Cleaner, Wong

Design permits the cleaning of four NMR tubes at the same time. With solvent in the reservoir, rapid suction wets the inside of the NMR tube dislodging the contamination. An acetone wash followed by an air stream dries the tube in seconds. Rate of cleaning is approximately 4 tubes per minute. The NMR tube is inserted into the cleaner with a poly-pro cap placed on the closed end to provide support and a vacuum seal.  Lower joint is a 24/40 inner, and the hose connection has an O.D. of 8.5mm at the middle serration. Complete unit comes with an NMR tube washer and 250ml heavy wall filter flask. NOTE: FOR USE WITH 5mm O.D. X 7in TUBES ONLY.
